Charles M. Lieber to receive 2016 Von Hippel Award for research on nanoscale wires
T
he 2016 Von Hippel Award, the Materials Research Society’s (MRS) highest honor, will be presented to Charles M. Lieber, Department of Chemistry and Chemical Biology, Harvard University. Lieber is being recognized “for pioneering contributions to nanoscience, defining the foundations of rational synthesis of nanoscale wires, characterization of their fundamental physical properties, and the development of applications of these materials in chemistry, biology, and medicine.” Lieber will present his award talk at the 2016 MRS Fall Meeting in Boston on Wednesday, November 30, at 6:30 pm, in the Grand Ballroom of the Sheraton Boston Hotel. For more than two decades, Lieber’s research on nanoscale wires (nanowires) has revolutionized nanoscience and nanotechnology by defining new paradigms for the rational growth, fundamental properties, and original applications of a broad range of functional nanowires and heterostructures. Lieber has made seminal contributions to the designed growth of nanowires in which composition, size, structure, and morphology can be controlled. Lieber demonstrated that carbon nanotubes (CNTs) could be used as templates for the synthesis of a broad range of transition-metal and main group carbide nanowires (NWs), which provide access to nanoscale metallic, superconducting, and semiconducting materials. He made a second breakthrough with the synthesis of freestanding (molecule-like), singlecrystal semiconductor NWs. Subsequently, Lieber has driven this field with the rational syntheses of a large number of Group III–V and II–VI
binary and ternary NWs, the growth of NWs with controllable doping, which has been central to developments demonstrating nanoscale devices, and the synthesis of molecular-scale NWs. He also pioneered the related heterojunction concept of radial core–shell NW structures, pushing this idea to the limit of single-crystalline multiple-quantumwell structures. Most recently, Lieber has discovered a previously unreported crystal-growth phenomenon unique to one-dimensional substrates termed Plateau-Rayleigh crystal growth, which allows for simultaneous modulation of axial and radial growth to yield threedimensional materials with complex, tunable morphologies. Lieber has also made pioneering contributions to characterizing the physical properties of these materials. He developed new applications of scanning probe microscopies to define the electrical and mechanical properties of individual CNTs and NWs, for example, showing how lateral force microscopy could be used to measure the elastic modulus and strength of individual NWs and CNTs. In addition, Lieber led early scanning tunneling microscopy efforts demonstrating that CNTs could exhibit fundamentally metallic or semiconducting electronic properties depending only on subtle changes in diameter and helicity, and moreover, illuminated curvatureand symmetry-induced energy gaps in “metallic” CNTs. Lieber reported a conceptual and experimental appr
